Abstract

Heat transfer is the science used to predict the energy transfer that may occur between materials due to differences in temperature. The teachings of thermodynamics define this transfer of energy as heat. Heat transfer not only explains how heat energy is transferred, but also predict the rate of heat exchange under certain conditions. In this study , two variables will be used, namely the water flow rate and the baffle distance. In which the flow rate variables will be used, namely the water flow rate and the baffles distance, in which the flow rate variable has 3 variations in the flow rate, namely 30 cm/s, 40 cm/s, and 50 cm/s and the baffles distance variable has 3 variations. Namely 8 cm, 11 cm, and 14 cm. The results of this study resulted in the performance of the heat exchanger, namely the heat flow rate where the variation of the flow rate of 50 cm/s and the baffle distance of 8 cm has a total transfer rate of 1184 W. Then for the effectiveness of the heat exchanger performance which has the highest value is the flow rate . water is 30 cm/s and the baffle distance is 8 cm. And the highest NTU value is at a water flow rate of 30 cm/s and a baffle distance of 8 cm. from the test results, it can be concluded that high effectiveness provides better heat exchanger performance and it exists at a water flow rate of 30 cm/s and baffle distance of 8 cm.
